MACHINE Flonl CUTTING sTAvEs Fos BARRELS, &c.

Specification of Letters Patent No. 465', dated November 20, 1837.

To all whom t may concern y j Be it kno-wn that I, THOMAS Pieck, of the town of Lenox, in the county of Madison and State of New York, have invented a new and use ful Machine for Cutting Staves for Barrels, which is described as follows, reference being hadto the annexed drawings of the same, `making part of-this specification. Y A, F ig.- l, represents the frame of the machine, made of sufficient size and strength to contain and support the several parts hereafter described: It consists of two longitudinal sills united byH cross sills siX posts ;two plates united by cross beams; having suit-able braces to strengthen the frame. At each end, between the plates, and resting on the end beams, are placed three vparallel ways B B B Z) b Z2, over which the carriages with the bolts move.l See also sectional view 5. The ends of the ways toward the center of the machine are mortised and tenoned into the two center cross beams, Y y, Fig. 1.

c c represent the carriages for holding and hinging forward the bolts to the cutters, hereafter described Each carriage consists of three parallel timbers, united by two crosspieces. The two outside timbers are rabbeted on the outside, forming tongues, which move in grooves formed by the two outside parallel ways, and the plates. `The center timber moves over the center way. On the top of this timber is fastened a rack D. The forward cross piece projects beyond the side of the carriage, on which projecting part is placed a movable jaw E, closed by a large wood screw F, for holding the bolt rlhis screw passesthrough the jaw, side timber of the carriage, center timber, `a-nd turns in a female screw in the other side timber. This side timber also Lforms the other side of the jaws. The screw is turned by a pin passing through the head of it. The rack is notched on bot-h sides,-the size of the notches being according to the thickness of stave required, and may be turned over whenever it is desired to cut a thicker or thinner stave Both carriages are made and operated in the same manner: G vibrating frame containing the knives for cutting the staves: This frame consists of two parallel timbers, united by two cross timbers.

Through the center passes an aXle H, on which it vibrates: this aXle moves in boxes in the ends of the two center posts, which project above the top of the frame to receive them. In the center of the frame and parallel with the side timbers is fastened another timber I. To the ends of this timber are attached by joints two reaching arms K K which have handsy working in the racks falling in the notches of the racks for preventing the carriages running back while the knives are cutting -pEach dog is atf tached by a joint to the ends of a rectangular piece of metal or slid-eS, witha slot T, in

the center thereof and fastened in an inclined position by a screw bolt U, to across timber V, resting on the ends of the two short posts formed into the plates of the main frame-near their ends. T'he bolt U, for fastening the slide, passes through the slot, and obliquely through the cross timber to which it is fastened, and has a broad `head `on one end and a screw and nut on the other. ,y

The dog B, is made conveXon the upper side and concave on the other side. It is notched or cut out near its point.

` A groove or channel commences from the lower or concave sideofthe dog, near the i point, and runs upward in an inclined plane and comes out in a feather edge on the conveX side aboutthe center of the dog, so 'that the said channel or groove is nearly in the shape of a wedge. In this channel the curved end or hand of the reaching arm moves when it recedes from the knife to take hold of a new notch of the rack and is made thus to move in order to prevent the reaching arm taking hold of more than one notch at each stroke. The-slide and screw' are for the purpose of regulating the dog for coarser or finer racks-being raised when a thick stave is to be cut, and lowered when a thin one is required. Both dogs are made Y alike.

The two center cross beams of the frame upon which the cutting is performed are made stouter than the two end beams, and

immediately under the knives they are faced with metallic plates W w. Each plate having a longitudinal groove X in the upper side running parallel with and near the edge thereof, filled with a strip of soft wood upon which the edge of the knife strikes after passing through the bolt. This plate is for preventing the wear of the beams by the constant sliding of the bolt over them. The horse power' for operating` the machine consists of a vertical sha-ft l, upon which there is fastened a crown wheel 2, which works into a bevel pinion 3, on the end of the line shaft for turning the same.

On the upper end of the perpendicular shaft l is fastened a lever or sweep 4, to which the animals are attached for propelling the machine. S represents an extension of the frame at right angles to the main frame, to contain and support the horse power.

Fig. :2 represents a perspective view of a metallic plate, with vertical sides to Vreceive the sweep, and a square boX in the'center which slips over the end of the perpendicu- Vlarshaft, which is also made square to fit the same; a key being inserted through an opening in the shaft above the sweep and boX for securing them together and to the shaft:-5, 6, 7, pulley, cord and weight for running back the carriage. Similar pulley, cord and weight are placed at the other end of the frame for ruiming back the other carriage.

Operations- The carriages being run back, as represented in the drawings-the bolts (previously steamed) being secured, the dogs adjusted, the hands of the reaching arms brought down to the racks, the horse moves round in the direction of the arrow, the crown wheel turns the pinion on the end of the line shaft, this turns lthe line shaft, which turns the crank in the other end of it, this moves the connecting rod, attached to the end of theJ pendulousrod which it vibrates with the vibrating frame and knives, knife descends and passes through the bolt and cuts off a stave, at the same time causing the hand of the reaching arm over this bolt bolt taking oif a stave, at the same time causing the first mentioned knife to rise and draw forward the bolt the thickness of a sctave for a new cut which is performed in the manner before described, the staves falling down in part of the center timbers upon which the cut-ting is performed. This operation is continued until the two bolts are entirelycut up. The hands and dogs are then raised and the carriages run back by the pulleys, cords and weights to receive new bolts. Vhen it is required to eut thick staves the position of the rack is reversed so as to bring the coarse side uppermost. The dogs are also adjusted to correspond with them by unscrewing the nuts and raising the slide and then screwing up the nut again.

The invention claimed by me the said THOMAS PEOK and which I desire to secure by Letters Patent consistsl. In the combination of the two feeding carriages with the vibrating knife frame, constructed and operating, substantially as above described.

2. The combination of the reaching arms and hands (attached to the vibrating knife frame for drawing forward the carriages) with the vibrating knife frame and feeding carriages, as before described.

3'. The above described method of regulating the feed of the carriages by means of the grooved dogs and slides used in combination. Y

4. The longitudinal channels in the metallic plates filled with strips of wood upon which the cutting is performed as above described.

The horsepower for propelling the machine is not claimed.
